Previously I used MS-DOS 1.44 MB bootable floppy and added BIOS files to CD-ROM image, so an emulated floppy needed to load CD-ROM driver and then you was able to flash the BIOS. Now I use open/free 2.88 MB floppy with FreeDOS instead, and BIOS files are kept directly on the emulated floppy, so no need to load all these CD-ROM drivers, so it also boots a lot faster.
The script itself is here:
Put all BIOS related stuff (flashing program/BIOS itself) into bios directory in the same place as this script is, lets call it create_bios_iso.sh, the listing will look like that:
